Togashi, Yoshihiro

Fourteen-year-old thug Yuusuke Urameshi spends his days skipping school and causing trouble for the adults in his life. Yuusuke regularly engages in street brawls against rival Kazuma Kuwabara and ridicules his childhood friend Keiko Yukimura. Filled with self-loathing and the burden of an alcoholic mother, Yuusuke sacrifices it all in a split-second decision—he tackles a small child out of the way of an oncoming car, losing his life in the process.

Spirit guide Botan intervenes, allowing Yuusuke to see how the people in his life react to his death; he is moved by the emotional ruin his loss causes his mother, Keiko, and even Kuwabara. Additionally, due to his death's heroic nature, he receives an opportunity to return to life from the Spirit World ruler's son, Koenma.

Koenma hires Yuusuke as a "Spirit Detective" and tasks him with solving a series of increasingly challenging paranormal mysteries. Battling and befriending demons such as the beautiful Kurama and hostile Hiei, Yuusuke further develops and utilizes his skills as a fighter. But as dark forces move in the Underworld, Yuusuke struggles alongside his companions to defend everything he took for granted.

Fujita, Kazuhiro

Ushio to Tora centers around the travails and battles of Ushio Aotsuki, who is constantly being stalked and aided by a gigantic, supernatural and sometimes invisible tiger-like monster.

Ushio's family maintains a Shinto temple in Japan, where ~500 years ago, his samurai ancestor battled that same tiger to a standstill, and eventually trapped him against a rock using a blessed spear called the "Beast Spear," which in addition to its intrinsic formidability as a weapon, can also endow its wielder with the martial ability of the ancestor who originally wielded it.

Ushio accidentally unsealed the cave Tora was trapped in. Initially, Ushio refuses to remove the spear pinning Tora down, but Tora's unsealed presence summons various monsters who wish to fight him, and by extension Ushio. Ushio is forced to free Tora, who would like to eat Ushio, but dares not since Ushio keeps the spear close by. The series focuses on their relationship, interspersed with battles against mythological foes, and with Tora's attempts to grapple with modern life.

Kinnikuman (a.k.a. Kinniku Suguru) is a cowardly, clumsy, moronic, gyuudon-devouring excuse for a superhero (or Choujin)... who just happens to be the prince of an alien planet. But despite his pathetic appearance, he is very honorable and can become quite powerful when he needs to be. With his sidekick Meat-kun and fellow Choujin's Terryman and Ramenman there to help him, Suguru quests to become the greatest Choujin on the planet. Whether with a combination of tremendous heart and stamina (The Burning Inner Strength) or the "Power of Friendship," Kinnikuman frequently defeats villians 10 times more powerful than him and often causes his enemies to have a change of heart and join him. Though he seems destined to be an idiot forever, slowly but surely Kinnikuman becomes worthy of the title "Hero."

Note: Between volumes 36 and 37 publication there's 22 years gap. From volume 38 onwards starts restarted in 2011 version.

Overdevelopment and crowding in Japan has forced many of its indigenous spirits and ghosts to lose their homes. Due to problems caused by the homeless spirits, a new profession was created, the Ghost Sweeper (GS). Private exorcists for hire; they serve only the highest bidder to survive in the cutthroat corporate world. Among this, the Mikami GS Company, led by Reiko Mikami and her two assistants, the teenage boy Tadao Yokoshima and the ghost girl Okinu, is said to be the best.

In the near future, large mecha called Labors are made to assist in various reconstruction projects in major countries around the world that are being threatened by global warming. In Japan, the government has enacted Project Babylon in order to conduct land reclamation. Labors are also being pressed into police and military service aside from civilian use.

However, terrorists are now attempting to use labors to make themselves heard, as well as common criminals, thugs and guerrillas. The National Police Agency established the Special Vehicles Division, an all-labor task force to combat the potential use of labors for criminal/terrorist activities.

Nishimori, Hiroyuki

On their first day of class, first-year high school students Takashi Mitsuhashi and Shinji Itou immediately become friends. The duo seems to have quite a bit in common on the surface. Both of them aspire to emerge as delinquents upon entering their new school, and they begin to wear obnoxious haircuts to make them stand out from other teenagers.

However, despite being a feared pair, these two students actually have more differences than similarities. Itou wants to use his fists to protect the weak, earning respect and admiration from his classmates. On the other hand, Mitsuhashi strives to be the strongest in Japan—striking fear in anyone watching him.

Regardless of these dissimilarities, the two are notorious for their remarkable fighting abilities, and their friendship thrives when they come together to throw fists. Whether it be a fight against the good or the bad guys, nobody can win against these two unusual delinquents.
